International research team obtains first high-resolution fossil coral record of environmental data off Hawai’i
For the first time, an international research team has succeeded in obtaining a high-resolution continuous record of environmental data from shallow-water corals off the coast of Hawai’i (USA) by coring fossil coral reefs. These cores were obtained during an International Ocean Discovery Program (IODP) expedition led by Co-chief Scientists Professor Jody Webster (School of Geosciences, the University of Sydney, Australia) and Professor Christina Ravelo (Ocean Sciences Department at the University of California, Santa Cruz, USA).
The expedition planning started in 2007 with a scientific proposal to find out more about sea level and climate change and to better understand coral reef formation. Corals record past environmental conditions in their skeletons. By analyzing the valuable material gained during the offshore expedition phase in September and October 2023 the team aims to look back in time.
The objectives of the Expedition 389 are
• to reconstruct sea-level change over the last 500,000 years
• to reconstruct the variability in climate
• to understand response of the coral reef systems
• to examine ancient DNA
• to explain volcanic history of Hawai’i.

The expedition is conducted by the European Consortium for Ocean Research Drilling (ECORD) as part of the International Ocean Discovery Program (IODP). IODP is a publicly-funded international marine research program supported by 21 countries, which explores Earth's history and dynamics recorded in seafloor sediments and rocks, and monitors sub-seafloor environments. Through multiple platforms - a feature unique to IODP - scientists sample the deep biosphere and sub-seafloor ocean, environmental change, processes and effects, and solid Earth cycles and dynamics.
The ECORD Science Operator has extensive experience working in sensitive ecosystems such as coral reefs, following seagoing expeditions to the Great Barrier Reef (Australia, 2010) and Tahiti (2005).
